Coastal Variations

David Cass did specially created for #ArtSpeaksOut this video work. Around the world, sea levels are rising. By now, we are almost all aware of this phenomenon. This artwork focuses on the sea, and specifically, the impact of rising sea levels on coastlines around the world. Without doubt, all coastlines globally will be impacted by rising water as the climate crisis unfolds and ocean temperatures rise, but on a local level the variations in rates of rise from place to place are dramatic. My research over the last few years has led me to creatively interpret data from tide-gauges. These devices allow us to see exactly what is happening at a local level over expended periods (from thirty years, to well over a century). They chart the height of the sea in relation to land and overwhelmingly confirm a global upward trend.
